Bring smooth, confident braking back to the rear axle with the Dynamic Friction brake rotor 604-31158, a DFC GEOSPEC coated blank rotor that installs as a direct-fit rear disc brake rotor. It's designed to meet the same form, fit, and function as the OEM rotor on the 2016-2026 BMW X1, 2018-2026 BMW X2, 2018-2025 MINI Cooper Countryman, and more.
- Premium iron castings: engineered with G3000/G11H18 iron castings for strength, stability, and durability.
- OE vane configuration: matches the original equipment vane configuration to support proper heat dissipation.
- GEOSPEC coating: DFC states it provides superior corrosion protection over zinc or conventional painting.
- Precision finish: CNC-machined to tight tolerances and mill-balanced, with a non-directional finish designed to promote faster break-in and smoother stops.
The rotor arrives ready to install with no additional pre-degreasing preparation needed. Fitment covers the 2016-2026 BMW X1, 2018-2026 BMW X2, 2018-2025 MINI Cooper Countryman, 2020-2024 BMW 228i xDrive Gran Coupe, 2021-2024 BMW 228i Gran Coupe, 2025 MINI Aceman, 2025-2026 BMW 228 xDrive Gran Coupe, and 2026 BMW 228 Gran Coupe — see the Buyer's Guide tab for the full list. Rotors wear as a pair; replacing both sides is recommended for even, balanced braking. Sold individually — this listing is for one rotor.
